SPECIFICATION forming m of Letters Patent No.376,9 '14, dated January24, 1888;

Application filed December 1, 1887. Serial No. 256,670. (No model.) a

To all whom, it may 'concerm Be it known that I, JAMEs O. RUssELL, of

Beaver Falls,in the county of Beaver'and State.

of Pennsylvania, have invented certain new and useful Improvements inMachines for Dividing or Splitting Metal; and I do hereby "declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled inthe art to which it perto tains tomake and use it, reference being hadv to the accompanying drawings,which form part of this specification,

My invention relates to an improvement in machines'for dividing orsplitting metal; and r 5 it consists in a stationary frame provided withfriction-rolls and a suitable support upon which the heated piece ofmetal is to be placed, the drop or machine-head having rig idly securedthereto the cutter or cutters for zo'splitting or dividing the metal,and two pivoted bearings, which carry one or more-pairs ,ofdrawing-rolls fordrawing the metal which is to be split to a uniformthickness just pre vious to splitting, as will be more. fully describedhereinafter. I

The object of'my invention is to combine in a single machine rolls fordrawing the metal which is to be split to a uniform thickness just prior"to the splitting of its end,

I whereby all of the split pieces have a uniform thickness, which 'isnot the case where the blanks are not rolled.

Figure 1 is a plan view of a machine which embodies my invention, therolls being shown in the act of rolling the piece of 'metal. Fig. 2 isasimilar view showing the metal being split just after having beenrolled. Fig. 3 shows a slight modification, and showing how two cuttersmay be used instead of one.

to A represents the sides of themachi'ne, which are secured to asuitable frame-work, B, of

any suitable construction. This frame-work A extends horizontally orvertically, according to the direction in which it is desired to havethe cutter or' cutters move. If the cutter is to have a horizontalmotion, the frame will extendparallel with the floor, and if the cutteris to operate vertically the frame sets vertically. Passing throughopposite sides of this frame-work A are the set-screws C, by means ofwhich the bearings for therolls D a may be adjusted in and out for thepurpose oi either to be of the form here shown or. any";

other that may be preferred, and are pivoted to the movable head H, ofany suitable con-- struction.

of a drop or by suitable machinery of any kind, as this forms nospecialpart of thisinvention. These bearings G are placed upon opposite sidesof the cutter or cutters I, by means 7 of which the metal is to besplit, and at the same time form bearings for one or more pairs ofrolls, J, by means of 'which the metal is drawn toa uniform thicknessjustprior to being split. The outer edges of the bearings G are providedwith a number of steps or shoulders, 0, according to the 'number ofrolls J D, and these steps or shoulders serve, by comingin contactwiththe rolls D, to force the rolls J against opposite sides of thepiece of metal which is to be rolled and split,-'and thus v i V a causethe rolls J as they move along opposite When the head H is movedforwardjor down-1 a ward, the ends of the bearings G catch in betweenthe rolls D, so as, to bring the rolls J against opposite sides of thepiece of metal, andas the'supports G continue their dowry ward or inwardmovement the rolls J roll or draw the piece of metal to the thickness itis to have just prior to being split. The cutter orcutters I are broughtin contact with the end'of the piece of metal, and the metal is splitor' divided anyregulated distance into f two, three, or more parts, asmay be desired. The object of rolling the metal, as here shown,justpriorto splitting is, that the piecesof metal in being heated willlose more or less, by sealing, and hence their thicknesses vary;considerably when they come to be splitor divided; ,In order to overcomethis trouble;

I make each of the pieces of metal which are to besplit slightly thickerthan is necessary,

PATENT O FicE.

The head H may either be operatedby'means Q and then roll them to oneuniform thickness, as is here shown. is to be divided into two or moreparts two cutters will be employed, as shown in Fig. 3, and thesecutters will be separated a suitable distance from each other to formthe central portion of the metal, as shown. If the metal is to bedivided 'into a greater number of parts, then the cutters must becorrespondingly changed.

The cutter is here shown as movable; but, if preferred, the cutter maybe made stationary and the frame movable, as may be preferred.

Having thus described my invention, I claim- 1. The combination of rollsfor drawing the piece of metal to a uniform thickness, movable supportsin which the rolls are journaled, rolls or bearings between which thesupports are forced, and the cutter or cutters for dividing or splittingthe piece of metal, substantially as shown.

2. The combination of the frame, the ad- In case the piece of metaljustable rolls D, connected to the frame, the head or drop, the cutteror cutters secured to the head, the pivoted supports carrying one ormore pairs of rolls, and the support upon which the piece of metal to beoperated upon is placed, substantially as described.

3. In a machine for splitting metal, the combination of anendwise-moving cutter or cutters, a stationary bearing upon which theheated piece of metal to be split is placed, and rolls for drawing orreducing the thickness of the piece of metal to a uniform thickness justprior'to the splitting, both the cutter and movable bearings for therolls being connected to the same head or drop, substantially as setforth.

In testimony whereof I affix my signature in presence of two Witnesses.

- JAMES o. RUssELL.
